[0024] The utility model provides the following technical scheme:

[0025] Embodiment one

[0026] Combined Figures 1 to 4 A high sealing steel fireproof door, comprising a door frame 1, a fireproof door body 2 is hinged in the door frame 1, a pushing mechanism 4 is arranged on the front of the door frame 1, and a pressing mechanism 3 is arranged on the left side of the pushing mechanism 4.

[0027] The pressing mechanism 3 comprises a connecting box 31, the connecting box 31 is arranged on one side of the pushing mechanism 4, a threaded rod 32 is arranged in the connecting box 31, a connecting plate 33 is rotatably connected to the rear end of the threaded rod 32, a long plate 34 is fixedly connected to the back of the connecting plate 33, a pressing plate 35 is fixedly connected to the back of the long plate 34, and a handle 36 is fixedly connected to the front end of the threaded rod 32.

[0028] Further, a rectangular opening is formed in the back of the connecting box 31, and the long plate 34 penetrates through the rectangular opening and moves, so that the long plate 34 can move through the rectangular opening.

[0029] Further, a threaded hole is formed in the front of the connecting box 31, and the threaded rod 32 is screw-connected to the inner wall of the threaded hole.

[0030] Further, the connecting plate 33 is slidingly connected to the inner wall of the connecting box 31, and the back surface of the pressing plate 35 is in contact with the front surface of the fireproof door body 2, so that the pressing plate 35 can press and limit the fireproof door body 2.

[0031] Further, the pressing plate 35 is provided with two, and the back surface of the two pressing plates 35 is provided with anti-skid lines, which further improves the stability of the limiting.

[0032] Embodiment two

[0033] Reference Figures 1 to 4 On the basis of embodiment one, the pushing mechanism 4 further comprises a fixed plate 41 fixedly connected to the front surface of the door frame 1, a fixed box 42 fixedly connected to the front surface of the fixed plate 41, a rectangular block 43 slidingly connected inside the fixed box 42, a pushing shaft 44 fixedly connected to the front surface of the rectangular block 43, and a supporting block 45 fixedly connected to the left side of the rectangular block 43, which facilitates the storage of the connecting box 31.

[0034] Further, the fixed box 42 is provided with a notch on the front surface, and the pushing shaft 44 penetrates through the notch, and the supporting block 45 is fixedly connected to the right side of the connecting box 31, so that the pushing shaft 44 can move through the notch.

[0035] In actual operation, when the device is used, first, when the fireproof door body 2 needs to be reinforced and sealed, the handle 36 can be shaken to drive the threaded rod 32 to rotate. Since the threaded rod 32 and the connecting box 31 are threadedly connected, and the connecting plate 33 can be slidingly limited on the inner wall of the connecting box 31, the rotation of the threaded rod 32 drives the connecting plate 33 to move. The connecting plate 33 can drive the pressing plate 35 to move towards the fireproof door body 2 through the long plate 34, so that the pressing plate 35 can press and limit the fireproof door body 2, and the fireproof door can be reinforced and sealed. In the process of use, it has good stability and reduces the existence of certain security risks.

[0036] When the pressing and limiting of the fireproof door body 2 needs to be cancelled, first, the handle 36 can be rotated in the opposite direction, so that the pressing plate 35 no longer presses the fireproof door body 2. At this time, the pushing shaft 44 can be pushed to drive the rectangular block 43 to move, and the rectangular block 43 can drive the supporting block 45 to move, thereby achieving the purpose of moving the connecting box 31, so that the pressing plate 35 is no longer located on the front surface of the fireproof door body 2, thereby facilitating the further opening operation of the fireproof door body 2, improving the convenience of operation and use, and facilitating the further operation and use of the staff.
